Oasis’s revamped London flagship store clocked up record sales when it reopened last weekend.

Shop assistants at the 5,000 sq ft store on Argyll Street now carry iPads and mobile Chip and PIN terminals to allow customers to pay for products.

A spokeswoman said sales were up at least 100% on the same day last year.

The shop also features personal stylists and spacious dressing rooms, fitted with sofas where customers can relax while transactions are processed.
